Abstract: Process for standardisation and stabilisation of Si semiconductor slices from different suppliers to make them suitable for treatment on prodn. lines for mfr. of bipolar or unipolar devices comprises (a) sorting the slices into classes, each class contg. only slices having a precipitation value within a certain range; (b) applying a thermal cycle of adaptation which is identical for all the slices in a given class so that a defect free zone 10-30 micron deep is created corresp. to a given no. of seeds (2.10 power 8 -2.10 power 9)/cm3 and (c) cleaning the slices.  More specifically the sorting step includes an initial step of sepg. the slices into different batches each batch including slices provided by the same source and presenting similar initial oxygen concns., esp. 26, 27-30, 30-33, 33-36, 36-39 and 40 ppmA of oxygen. The value of oxygen pptn. is determined by a test of 20h at 900 deg.C in N2 atmosphere with samples taken from each batch. Other methods are also used, the steps required for obtg. a defect free batch are determined from the overall results.

Abstract: Method of straight-line drawing for reducing the cross section of round material, tubing, solid and hollow profiles in at least two drawing stages, which includes feeding material to be drawn with a leading end to a first drawing machine for a first drawing stage, feeding the material to be drawn with the leading end in a straight line downstream of the first drawing machine. Subsequently the material to be drawn is fed with the leading end to at least one second drawing machine having a linearly movable intermittently operable drawing carriage operating at a discontinuous speed at the beginning of the drawing while said first drawing machine is already operating continuously, being disposed downstream of the straight line for at least one second drawing stage. Next, the material to be drawn from the straight line upstream of the second drawing machine is deflected as soon as the leading end of the material to be drawn has reached the second drawing machine, and the length of the deflected material is varied for equalizing differences in feeding speed between said first and second machine.

Abstract: A hydraulic device such as a double acting cylinder is driven by a pump in turn driven by an engine.  Supply from the pump to opposite sides of the piston is controlled by an electromagnetically operated valve.  A second electromagnetic valve controls two pistons combined with the pump to vary its output.  The operating handle for the cylinder is connected to a nominal value signal emitter which controls both electromagnetic valves. Both valves act proportionally in one of several alternative control arrangements, an additional signal is injected at a summing point following the signal emitter.  This superimposes a minimum flow additional to that supplied by the valves.

Abstract: A hysteresis circuit is disclosed in which a first signal path, including a hysteresis feedback loop, is separate from a second signal path that is used to carry data. When the signal input to the hysteresis circuit (also referred to hereinafter as the "input signal") crosses a first preselected hysteresis reference (of "threshold") level, the hysteresis feedback loop, which includes threshold adjustments means, will cause a change in the threshold from the first preselected level to a second preselected level. This adjustment of threshold level will take place in parallel with the data being propagated to the output over said separate second signal path. A subsequent crossing of the second preselected threshold level by said input signal will cause the first threshold level to be reset and so on. According to the preferred embodiment of the invention, the threshold adjustment means included in said first signal path further includes a temperature compensation string, current switching means and means which act as an anti-hysteresis killer to speed up the operation of the hysteresis circuit. This novel combination is operative to assure a preselected minimum hysteresis window over the 200 DEG C temperature range between -55 DEG C and 155 DEG C, and renders the hysteresis circuit suitable for use in both military applications and other hostile environments. Furthermore, according to the preferred embodiment of the invention, the hysteresis circuit has a PNP input stage to reduce IIL and acordingly improve the input characteristics of the circuit, particularly fan-in. The circuit also features a low ICC and is designed to be self-compensating with respect to manufacturing disparities inherent in components used to fabricate the circuit itself.
